Measure in Cube Appearing Too Large by a Factor of 10

I have 2 measures in my cube, hours worked normal and total hours worked.

Total hours worked is a calculated measure which is:

hours worked normal + hours worked overtime + hours worked flex

This is showing correctly when I compare with the values returned from the database table. All these fields are sourced from the same database table. However when I drop hours worked normal by itself into the cube it is coming up too large by a factor of 10. Anyone have an idea what might cause this?
